• A gentle machine cycle at 30°C
• Use a mild detergent
• Wash like with like: similar colours, similar fabrics
• Turn black tee inside out to preserve the shade
• Avoid fabric softeners, bleach, or stain removers
• Only wash when necessary - often, simply airing is enough
Do not overcrowd the machine: too much friction wears fibres down. If hand-washing, gently swirl, never wring or twist.
